Diffy Integrations: CI/CD, Hosting and Dev Tools

Diffy compares screenshots of your pages across environments. These integrations decide when that happens — on a pull request, after a deploy, from your laptop — and where the result goes: a check on the pull request, a merge request comment, Slack, or a ticket in your tracker.

Anything that can run a shell command with PHP installed can run Diffy through the Diffy CLI, and anything that can make an HTTP request can call the API directly (API access comes with every paid plan). The integrations below are the ones with a ready-made setup or a written guide.

CI/CD and code hosting

Integration	What it does	Guide
GitHub Actions	Compares every pull request’s preview environment with production and posts the result as a check on the pull request, with an optional comment	Visual regression testing in GitHub Actions
GitHub checks and comments	The Diffy GitHub app attaches a check to the commit: success when nothing changed, action required when changes need review, success again once they’re reviewed. Can be a required status check	GitHub Actions guide
GitLab	Posts a comment on the merge request when the comparison starts and another when it completes, and sets a commit status	Visual regression testing in GitLab CI · Docs
CircleCI	Runs Diffy from CircleCI pipelines	GitHub, Pantheon and CircleCI docs · Diffy CircleCI orb
Any other CI	Bitbucket Pipelines, Jenkins and other runners call the same CLI command	Automation overview

Hosting platforms and preview environments

Diffy needs a URL for each environment it compares. These guides show how to get that URL from your host and hand it to Diffy automatically.

Platform	What it does	Guide
Upsun (formerly Platform.sh)	Waits for Upsun’s pull request environment, then compares it with production	Upsun pull request guide
Pantheon	Creates a Multidev for each pull request and compares it. A separate script runs CMS updates on their own Multidev and compares the result	GitHub, Pantheon and GitHub Actions docs · Blog: Pantheon deployments from GitHub · pantheon-autoupdates
Tugboat	Triggers the comparison once a Tugboat preview has built	GitHub and Tugboat docs
Cloudflare	Compares a Cloudflare branch deployment with production after the deployment check succeeds	Astro, GitHub and Cloudflare docs
Vercel and other hosts with GitHub deployments	Triggers on GitHub’s deployment_status event and compares the preview URL	GitHub Actions guide

CMS

Integration	What it does	Guide
WordPress	Tests what core, theme and plugin updates change, staging against production or before against after	WordPress visual regression testing
Drupal, WordPress and Netlify logins	Built-in login presets, so Diffy can screenshot pages behind a login	Project settings → Authenticate

Local development

Test your local site before you push: capture screenshots on your machine with one of the add-ons, or open a tunnel so Diffy’s servers can reach it.

Slack	Posts results to a Slack channel, including the AI Summary when it’s enabled	Diffy AI
Webhooks	Sends results to any URL, for your own automation	Diffy AI
Zapier	Creates tickets in Jira, Asana, Trello, Basecamp and other trackers from Diffy	Zapier docs

Missing an integration?

If your stack isn’t listed, it most likely works through the CLI: get the environment URL, run diffy project:compare, and read the result from the check, the comment or the notification. Tell us what you use at support@diffy.website — new guides come from those requests. Or start a free account and try a comparison from the UI first.
